D3.js 如何使用Cubism.js进行“一次准备，多次回调”

D3.js Cubism.js。。。漂亮的工作。 我尝试将Cubism.js与自己的数据源一起使用，需要同步显示多个地平线图。 更新的间隔非常短，小于1s，这就是为什么我需要从数据源批量获取值-所有这些都在一次调用中。 如果在比较请求的START、STOP和存储的lastSTART、lastSTOP时加载最新数据，则会做出此决定。 它在我的代码中工作，但我不知道如何正确地为每个地平线图调用数据更新回调函数。 At显示仅更新最后一个图形。 有人能帮我解决这个问题吗

代码：

PHP后端： 仅用于模拟目的-返回带有时间戳值的命名数组的JSON对象 可能类似于Cube.js
